Abstract
The excursion of a loudspeaker cone is estimated using a reference signal in one example, a primary signal, produced by a cone of a loudspeaker, is received and a reference signal produced simultaneously with the primary signal by the loudspeaker cone is received. The reference signal causes an excursion of the loudspeaker cone that is amplitude modulated by the excursion caused by the primary signal. An amplitude modulation of the reference signal is determined and an excursion of the loudspeaker cone is determined using the determined amplitude modulation.
